Installation Notes from Our Crew

REC Alpha Pure-RX 470W

REC Alpha Pure-RX is our go-to premium panel. The 470W output means fewer panels for the same system size, which reduces racking hardware and labor. HJT cells have near-zero LID (light-induced degradation), so these panels produce at full rated power from day one. We recommend REC for space-constrained roofs where every watt per square foot counts.

Maxeon 7 475W

Maxeon 7 is the Ferrari of solar panels. The IBC cells produce noticeably more energy on partially shaded roofs — we've measured 10-15% more output vs standard panels in real-world shade conditions. The solid copper backing means we've never had a micro-crack warranty claim. We recommend this for customers who plan to stay in their home 20+ years and want maximum lifetime production. The 40-year warranty is unmatched.
